Referrin to the drawings in detail, it will be seen that the numerals 5 denote two longitu dinally extending supporting bars, which inthe present instance rest at their forward en'dson the front axle G and are held in place by suitable means 7 a and these bars curve under the rear axle-assembly as at 8 and are clamped thereto as at :9 and -extend'reari I to Cross bars 10 are mounted on the bars 5, I one ,to the rearof the front axle and one to the rear -of the rear axle. Plates '11 are hingedly engaged as at 12, with the ends of the cross bars 10 and rise'there'from and are urged rearwardly by means of springs 14, secured to the cross bars, lO-and to the upper ends of the plates 11. Curved flexible strap-like checkers are fixed to the upper and forwardly over wheels 16 and then; down-- f wardlyin front of the wheels to terminate normally a distance above the ground.

A movable frame comprises a pair of longiprovided with side sectional tu'clina-l members 18 held in spaced parallel [relation and co-extensive' bv-means of cross I braces 19.

1 The chassis of the vehicle is indicated at 2.7 and is located below the movable .frame,

' but above the bars 5 and 10. The guides extendto the outer sides of the sides of the f chassis; The movable frame is held in a rearward position by means of the spring 28,

anchored as at 29, on the rear axle assembly and -to the rearmost cross member in, as at 30. A shank 3l rises from thesecond from 'jacent the forward portion ofthe wheels 16. l

in the floor board 33 and has a foot plate 34, on the upper end thereof. A lever 35 extends laterally from an intermediate portion of the shank above thefioor board 33, and

then upwardly.

From the above detailed description, it will be seen that the shank 31 and the movable frame may be urged forwardly, either by foot power or by hand, and when-moved forwardly, the frame causes the rocking of the plates ll'forwardly, and thereby swing the checkers forwardly and downwardly to engage withv the ground and then under the wheel thus positively preventingthe' rotation 0 the wheels and causing a sliding until the vehicle comes to a dead stop, and this sliding strain ison the checkers rather than v on the tires of the wheel.

Thus skidding is prevented, and a quick and safe stop is ef- It is thought that the construction, oper ation, utility and advantages of.the invention will now be clearly understood by those skilled in.thisv art, without-a more detailed description thereof.-,

The present embodiment of the invention" has been disclosed in detail, merely for the purpose of exemplification, since' in actual practice, it attains the-features of advantage enumerated as desirable, in the'statement of the invention and the above description.

It willlbe apparent that changes in the details of construction, andin'the combination and arrangement of parts may be resorted to,

without departing from the spirit or scope of the invention or sacrificing any of its ad- Having thus described my invention, what Lclaim as'new is:

1. An apparatus of the class described, in-

. eluding a stationary frame structure, means for mounting the frame structure on a vehicle, a movable frame structure, aplurality of .fiexible strap like checkers, one for each wheel of the vehicle, means forhingedly e'ngaging the checkers with the stationary frame, a movableframe, means engaging the movable frame with intermediate portions of the checkers, spring means associated with the checkers holding them normallyin a predetermined position, spring means associated with the movable frame holding it in a nor- .mal predetermined position.

' com risin a air of Ion itudinal bars- 2. An apparatus ofthe class described means, for fixing the bars to the axles of a vehicle, cross bars on the first mentioned bars,

plates hinged to the cross bars, springs en gaged with the plate and the crossbars to hold the plates in a normal predetermined position, a plurality of strap like flexible checkers engaged with the upper ends of the plates and curved over the wheels of the vehicle, a movable frame having rising arms provided with pintles, and means enga ing the pintles with intermediate portions 0 the checkers.
